What instrument is used to collect humidity? hygrometers What instrument is used to collect wind speed data? anemometer How is weather data collected? Collecting Data Weather instruments collect data from all over the world at thousands of weather stations (figure below). Many are on land, but some float in the oceans on buoys. Weather stations […]

What is the opposite of terminal velocity? Terminal velocity is the speed when an object falling through a fluid (usually air) is no longer getting faster. Terminal velocity happens at the moment in time that the force of gravity, called weight, is the same as the opposite force of air resistance or friction. What is […]

How many times is the rms speed of molecules in 8gm o2? here, R = 8.314 J/moleK = 8.314 kg m²./ s² , M = molar mass, T = temperature in kelvin. The rms speed of a gas changes if its temperature changes. there is no effect pressure and the weight of gas on the […]

Where do you put anti seize on brakes? Use the Right Lube Anti Seize: The only place to sparingly use anti seize lubricant is on the brake rotor center hole, where it rides on the wheel hub. On caliper slides, it will dry out and seize up, but not before destroying the rubber boots. Can […]

How is energy stored in a field? the energy stored by the electric field is expressed in its capacitance. it stores it like a stress or a pressure in the region of space where dielectric or dipole charges are present like in a capacitor. the closer the space between the capacitor plates the greater is […]

Is H2O a single or double bond? Now, in water, i.e. H2O, oxygen is the central atom and can either form one double or two single bonds. We have two hydrogens which can only form single bonds. Thus, in water, oxygen is singly bonded to two hydrogen atoms. Carbon can form four bonds while oxygen […]

What was the last period of dinosaurs? Cretaceous Period What were the two major types of dinosaurs? With the discovery of many new species since the 1840s, the Dinosauria now contains two major groups of dinosaurs: the Ornithischia, or “bird-hipped” dinosaurs, and the Saurischia, or “lizard-hipped” dinosaurs. The division between the two groups was made […]

What if you fall in a dam? If the dam has an open discharge system with consistent flow, you might break a few ribs, bump your head, etc. If you fall down this dam, you may risk drowning and also maybe a water spilled brain, but you may actually survive because there is lots of […]

Why do we need diversity? Diversity brings in new ideas and experiences, and people can learn from each other. Bringing in different ideas and perspectives leads to better problem-solving. Working in diverse teams opens dialogue and promotes creativity. The value of diversity is true for our culture, too. What are the three components of biodiversity? […]

When one object exerts a force on a second object the second object exerts the same amount of force of the first? Newton’s Third Law – When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for […]
